Unlike amplifiers speakers cannot hide their faults from measurements.
You can't measure a dipole loudspeaker in the near field and get worthwhile results. You also can't listen to a Magnepan placed one foot from the front wall and surrounded by other gear. Magnepans lead the industry in each of their respective price ranges including the very top end of audio loudspeakers. Measurements are fine when they are measuring things that can be accurately measured, dipoles are not one of those things. Get out and go listen to a 3.7 or a 20 and you'll see what we are talking about.
